Question

The number of girls in a class is $3$ times the number of boys. Which of the following cannot be the total number of students in the class?

• A. $24$
• B. $32$
• C. $36$
• D. $41$

Answer 1

The correct option is D $41$

Let the number of boys be $x$
Thus the number of girls $=$ $3x$
Total students in the class $=$ $x+3x=4x$
Now, verifying with the options,
A) $4x=24\Rightarrow x=6$
B) $4x=32\Rightarrow x=8$
C) $4x=36\Rightarrow x=9$
D) $4x=41\Rightarrow x=\frac{41}{4}$.
Since number of boys cannot be in fraction, therefore, option D is not possible.
